For this one, you will need to keep all the police out from the warehouse on day 2. Jokers count.

For this metod, you will need at least 3 sentries with AP rounds enabled. It is recommended for you not to bring a flamethrower, as bulldozers will be a problem.

You will need to put sentries on every entrance (Except from the upper floor ones).

Be careful, as bags that are carried to the escape won’t count for the achievement. Also, don’t put the bags inside the warehouse, as police will go straight forward to the warehouse to get them.

There are some modificatons when you play on Mayhem and above:

- A Skulldozer and 3 shields will be guarding the bags
- The warehouse will be locked

In other words, if you secure all the bags on mayhem+, you will have the achievement granted.
